Idea: use partial translations to give people the confidence to do complete translations.

Partial translations could use the best translations so far to fill in some of the sentence while leaving out parts that you should be able to translate given the vocabulary that you should know.

Good idea, although I think that it may be hard to implement. Nevertheless it would solve to some point the problem of too hard and too long sentences - those discourages me very much from making translations.

I wonder if there would be a copyright issue here though as sentences would be transformed for educational purposes — not just for translation of the original document.
